Specification of Letters Patent.

Patented June 22, 1909.

Application filed November 17, 1908. Serial No. 463,010.

To all whom it may concern:

Be it known that I, JOHN P. ARonDEAooN, a citizen of the United States, and a resident of Boston, in the county of Suffolk and State of Massachusetts, have invented a new and Improved Mold for Making Fluted Columns, of which the following is a full, clear, and exact description.

The object of the invention is to provide a new and improved mold for making fluted columns of cement, plaster or other plastic material, the mold being arranged to ermit of building the column at the intendcc place on a building or in a shop, and giving it the desired tapering form and producing the flutes on the exterior surface with gradually less depth and width according to the taper of the column.

The invention consists of novel features and parts and combinations of the same, which will be more fully described hereinafter and then pointed out in the claims.

A practical embodiment of the invention is represented in the accom anying drawings forming a part of this specifi cation, in which similar characters of reference indicate corresponding parts in all the views.

Figure l is a side elevation of the improvement as applied, parts being in section; Fig. 2 is an enlarged sectional plan View of the same on the line 22 of Fig. 1; Fig. 3 is an enlarged sectional plan view of the i1nprovement on the line 33 of Fig. 5; Fig. l is a sectional side elevation of the same on the line 44 of Fig. 3; Fig. 5 is a cross section of the same on the line 5-5 of Fig. 3 Fig. 6 is an enlarged sectional plan view of the improvement on the line 6-6 of Fig. l, and showing the former at a point removed from the base of the column; Fig. 7 is a plan view of one of the airs of knives and the arms for opening anc closing the knives; and Fig. 8 is a cross section of the improvement on the line 8 8 of Fig. 6.

The core A of the mold is preferably in the form of a hollow cylinder and may be set on the foundation of the column B, to be built up of cement, concrete, plaster or other suitable plastic material placed while in plastic state by the workmen upon the exterior face of the core from the foundation upward, as the forming of the column progresses; and in order to provide the exterior surface of this plastic material B with the usual alternating flutes B and fillets or ridges B and to gradually diminish or taper the column, use is made of a former C gradually moved upward as the building of the column advances.

The former C is mounted on uprights D, preferably four in number, grouped around the core A and spaced from the same, as plainly indicated in Fig. 2, the lower and upper ends of the uprights D being connected with each other by connecting bars D and D (see Figs. 1 and 2), to form a rigid although temporary structure. Each of the uprights D is provided at each of its sides with guideways D, D, of which the outer guideway D is disposed vertically while the inner guideway D is inclined inwardly, as plainly shown in Fig. 1. In the outer guideway 1) is mounted to slide up and down a slide E, provided with a bar E extending inwardly and attached to a cross bar E connecting the ends of segmental bars E E" with each other, the outer segmental bar E being also connected by a bar E with the slide E. The slide E, the bars E, E, the cross bar E and the segmental bars E, E between adjacent supports D, form a rigid section of a skeleton former frame, and in order to move the four sections in unison and gradually upward, as the building of the column progresses, the following arrangement is made: On the slide E is secured or formed a hook E engaged by one end of a cord or a chain F, extending upwardly and passing over pulleys .F, F 2 mounted on the 11 )per end of the corresponding upright D. ii weight .F is attached to the upper ends of the cords F of the two slides E for one upright D, and the said weight F is also connected with two cords F likewise passing over the pulleys F F and over the pulleys F mounted on the upper ends of the uprights D, to direct the cords F downward on opposite sides of the uprights D, and to allow their attachment to hooks G on brackets G adjustably secured by bolts G to slides H, mounted to slide up in the inclined guideways D of the corresponding upright D. Thus the weight F of each upright D counterbalances the slides E and H and the parts supported thereby, to allow convenient upward movement of the former C as the building of the column B progresses. Each of the brackets G is provided with transversely extending slots G through which pass the bolts G to allow of adjusting the brackets G transversely on the slides H.

' hereinafter more fully explained.

On each bracket G is formed a shelf G on which is secured by bolts G a push plate I in the form of a segment of a circle and overlapping a similar push plate I attached to the shelf G of the bracket G on the next following upright D, as will be readily understood by reference to Fi 2. Each of the ush plates I is provided with elongated slots T through each of which extends a pivot J forming the fulcrum of the crossing members K and K of a lazy tong, ranging in segmental shape from one upright D to the next following one, the members K and K of the lazy tong being provided at their outer ends with elongated slots K for the passage of a ivot K and the inner ends of the members K are connected with each other by pivots K so that when the push plates I are moved inward the lazy tongs are closed, as

The pivots K K extend in the slots L of radially disposed arms L, resting on and secured to the bars E E by clamps E attached to and forming part of the bars E E of the former frame previously mentioned.

Each pivot K is provided with a washer K extending between the bottom member K and the corresponding arm L, and from the washer K depends a guide pin K, also extending into the slot L of the corresponding arm L, the same as the pivot K (see Fig. 5), the arrangement allowing easy sliding of the pivot K in the slot L of the arm L. Each of the pivots J rises from a plate or '7 washer J extending between the member K and a radially-disposed arm l secured by the clamps E to the bars E E of a former frame section, and from each washer J depend guide pins J extending into a slot N of the corresponding arm N. The slotted radial arm L adjacent to an upright D is also engaged by a guideway E attached to the slide E and having bolts E passing through the slot L. The bolts G of the shelf G previously mentioned also pass through the slot L of the arm L adjacent to the upright D, as will be readily understood by reference to Figs. 3 and 5.

The arms L and N alternate and are radially disposed relatively to the flutes B and the fillets B of the column B, and said flutes B and the fillets B are formed by sets or pairs of knives O, O secured to the inner ends of the lazy tong members K, K. The knives O, O are adjustably secured to the lazy tong members K, K by screws P screwing in the members K, K and passing through elongated slots in the knives O, O, as plainly shown in- Fig. 7. The lazy tong members K, K are also provided with guide pins K extending into elongated slots 0 formed in the knives O, 0, so as to properly guide the knives one over the other on closing the members K, K of the lazy tongs. The knives O, O of a pair of knives form a semi-circular cutting edge 0, for forming the flute B, and from the ends of the semi-circular cutting edge 0 extend sidewise the straight cutting edges 0 for forming the fillets B it being understood that the knives O, O of adjacent pairs overlap each other, so that the two straight cutting edges 0 of the over-lapping knives O and O of adjacent pairs completely cover the fillet B as will be readily understood by reference to Fig. 3.

On the inner end of each member K is pivoted a scraper Q underlying the knives and having an elongated slot Q engaging a pin Q on the inner end of the member K of the next adjacent pair of members K, K (see Fig. 6). The scrapers Q follow the knives and scrape the outer faces of the fillets B true. By having a scraper Q connecting the links K, K on opposite sides of a support D with each other, it is evident that the four lazy tongs, ranging between the several supports D, are connected with each other, as will be readily understood by reference to Figs. 2 and 6. The lazy tong members K adjacent to the supports D are shortened and connected by links K with the lazy tong member K next following, so that the connected lazy tongs open and close simultaneously with each other.

The operation is as follows: The mold is set up centrally at a place on the building on which the column is to be erected, or the mold is set up in a shop in case it is desired to make columns and ship the same to their destination. Then the mold is set up the former C is at the bottom, and then the workmen place the plastic material B against the outside of the core A, to a de sired thickness and a suitable working height, and then the former C is raised so that the sets of knives O, 0 form the flutes B and the fillets B on the outer face of the plastic material, that is, the surplus material removed by the knives O, O and resting on the top thereof is removed by the workmen as the former C rises. The column is gradually built up in the manner described, and as the former C rises, the slides H move inward bodily on account of traveling in the inclined guideways D and this inward movement of the slides H causes a like inward movement of the push plates I, so that the pivots J thereof act on the members K, K of the lazy tongs to close the same gradually, thus causing the knives O, O of each pair to gradually move over each other and thus reduce the cutting edges 9 thereof, both in shape and depth, as will be readily understood by comparison of Figs. 3 and 6, Fig. 3 showing the knives O and 0 near the base of the column while Fig. 6 discloses the position of the former C at a distance above the base. By having the several sections of the former arranged in the manner described,

it is evident that they move practically together, and the desired taper is given to the column, and at the same time the flutes B and the fillets B are properly formed with gradually less depth and width. By having the scrapers Q following the knife extensions Q it is evident that the fillets are scraped perfectly true, as will be readily understood y reference to Fig. 6. By having the knives O and 0' adjustable on the lazy tong members K, K and by adjusting the radial arms L and N on the bars E, E of the former frame, it is evident that the same former can be used for forming flutes B and fillets B of different depth and width for different sized columns. In practice, a former can be used for columns running from eighteen inches in diameter to say twenty inches in diameter, but with the addition of extra knives the former can be used for smaller or larger sized columns. After the column has been built, the sections of the mold can be readily taken apart, so that the column is left standing at its intended place on the building, and the mold can be set up in another place for forming another column in the manner described.
